File Parsing By NASA

Curve fitting is one of the most important processes of the engineering curriculum. To analyse any unknown data curve fitting is a must. So by the use of python the thermodynamic data of the specific heat at constant pressure of oxygen against the temperature is analysed and plotted against the given data.   The curve…

The code of the Otto Cycle is defined by the following python program  \"\"\" Otto Cycle \"\"\" import math import matplotlib.pyplot as plt def engine_kinematics(bore,stroke,con_rod,cr,start_crank,end_crank): \"\"\" Engine Kinematics \"\"\" # Setting the initial variables a = stroke/2 R = con_rod/a Vs = math.pi*(1/4)*pow(bore,2)*stroke…

File parsing is an important aspect of data handling in MATLAB. In this project the data of the file \'therm.dat\'. The objective is to extract the coefficients of the gas to apply in the equations as follows to obtain the Cp, H and S value over the range of temperature given in the file. The main code is as follows clc…

GENETIC ALGORITHM OVERVIEW Genetic algorithm is based on the \"Theory of Natural Selection\" as proposed by biologist \"Charles Darwin\". This is also known as Evolutionary Algorithm. Genetic algorithm works on the principle of evolution  and natural selection. 1. At first the random population is selected from the…

The curve fitting is the most basic and important process to assess the mathematical model of the unknown data set. It is like finding the unknown equation out of the data set. To understand the process we take the following example of the change of specific heat over the temperature range.   Now for the fitting data…

The oscillation of simple pendulum is a phenomenon occurs in everyday objects like bell, chime, old wall clocks, etc. But the oscillation seemingly going to end at infinity are actually damped by nature, meaning the amplitude of oscillation is decreasing per time. The decrease in amplitude can be due to various reasons…

The flow over the cyclist is defined by the drag force acting on the cyclist. the drag force of the air is given by the equation  F = 0.5*cd*A*v^2 cd = Coefficient of drag A = Frontal area of the cyclist v = velocity of the cyclist   The MATLAB code for plotting graphs  clc clear all close all % drag force…
